Summary
The dam serves multiple purposes including flood risk reduction, fire protection, stock, fish and wildlife pond, with a primary height of 33 feet and a hydraulic height of 31 feet. The dam has a storage capacity of 79 acre-feet and covers a surface area of 2 acres, with a drainage area of 111 square miles.
The dam features an uncontrolled spillway type with a width of 20 feet and outlet gates also uncontrolled. It has a low hazard potential and a moderate risk assessment rating of 3. Although the condition assessment is not rated, the dam has been inspected every 5 years since its completion, with the last inspection conducted in September 2001. The dam is situated on the TR-Locust Creek and is part of the Rock Island District, with no state regulation or permitting requirements.
Overall, Upper Locust Creek L- 89 plays a crucial role in flood risk reduction in the area and contributes to various ecosystem services. Its strategic location in Browning, Missouri, highlights the significance of sustainable water resource management in mitigating climate-related challenges. With its relatively low hazard potential and proactive inspection schedule, the dam stands as a key infrastructure asset for the community, ensuring the safety and well-being of residents and wildlife in the region.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
